Rabbit Racing - Universal Oil Catch Tank AN10 made of aluminum / 750ml

What do you need an oil catch tank for?

During engine operation, a so-called crankcase pressure is created in the crankcase. This pressure (consisting of oil vapors) forms when the oil gets hot and the crankshaft is immersed in the oil with every revolution.

This crankcase pressure must be routed out of the engine, otherwise seals and components will be damaged. Every engine has a ventilation system, which usually consists of two openings. One is on the engine block and the others are on the cylinder head cover. Hoses and a pressure control valve are connected there, which leads the oil vapors back into the intake paths unfiltered (!). The oil vapors are therefore added to the combustion process and burned with it. However, this inevitably leads to various problems:

Knock resistance decreases, which increases the risk of engine damage

Injection valves, throttle valves, turbocharger compressor housing, intercooler, sensors and intake valves are constantly wetted with oil vapors, which in the long run leads to coking on the intake valves and intake ducts - the result? It can e.g. cause the valves to tear off

Rough idling, misfiring, loss of power and increased fuel consumption are also a result of unfiltered oil vapors

The solution: An oil catch tank

An oil catch tank filters out the oil vapors from the crankcase ventilation. The oil condenses in the oil catch tank and collects in the container. The air that has been cleaned of oil is then fed back into the air filter box or released into the open air.
